I think I have about 40 gallons in the water heater. If by the end of today the water still isn't on I might shut off the water heater first and then drain some into a bucket for flushing. ( I got a short hose to help )
Probably not a good idea to drain a water heater with the gas or electric still running.
I would keep it for survival water but the roads work and we got a lot of water out and about yesterday.
Also I had managed to save some water in the bathtub ( I had been using it as a heat mass ) and got caught at just the wrong time or I'd have more water in there.
